| Abstract: | Through an elastic-plastic analysis of FLAC3D program based on the explicit difference method,and from the case of urban complex of the third space deep excavation project in Tangshan on composite soil nailing combined with general soil nail and prestressed anchor.Numerical simulation is carried out and the horizontal displacement on the top of pit foundation,with measured date is discussed.The analysis shows that the composite soil nailing can largely restrain the pit foundation deformation.The successful ... |
